One of my favorite oatmeal recipes to date is this stove top recipe for peanut butter banana chia oatmeal. Peanut butter and banana are simply the best oatmeal combo in my personal opinion and I’m honestly surprised it took me so long to come up with a baked oatmeal recipe that has both!

I thought it would be fun to kick off the New Year with a new baked oatmeal recipe that’s perfect for all your healthy eating goals. No matter how much you indulged over the past few weeks (or months!) you can always decide to make a change. Start with one small change… like eating a healthy breakfast every day!

Why is Eating Breakfast Important?

Breakfast is often deemed the most important meal of the day? Isn’t it funny that it’s probably the most skipped meal of the day? So why is it so important anyway?

  • Kick start your metabolism – The earlier you eat in the day, the more calories you’ll burn! Seriously.
  • Energy – Food=fuel. Eating breakfast will give you energy to get important tasks done all day long.
  • Concentration – Do you notice that you can’t focus on anything but food when you’re hungry? THAT is why eating breakfast improves concentration throughout the day!

Make this simple peanut butter banana baked oatmeal on Sunday and have delicious, healthy and quick breakfasts to enjoy all week long. You can eat it cold or pop it in the microwave or toaster oven for a bit to warm it up before enjoying. The perfect on-the-go breakfast.

Peanut Butter Banana Baked Oatmeal Recipe

I sound like a broken record but this recipe is so simple to make! Start by mixing the dry ingredients together in a large bowl. Mix in the wet ingredients as well as two sliced bananas. Stir well to combine everything. Pour the mixture into a baking dish that has been sprayed with cooking spray and top with additional banana slices. Bake until golden brown, drizzle with more peanut butter and enjoy! You just made the best gluten-free, dairy-free breakfast around. 😉

Can You Make Baked Oatmeal Ahead of Time?

Yes, you can totally make baked oatmeal ahead of time. There are two options that work really well.

Option 1: Bake and Then Reheat Before Serving

  1. Prepare baked oatmeal as the recipe suggests. Once baked, let the oatmeal cool, cover the baking dish and place in the fridge. You can do this 1-2 days in advance.
  2. When you’re ready to serve, take oatmeal dish from fridge, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set toaster oven to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.

Option 2: Prep as Much as You Can Without Baking

  1. Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
  2. Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
  3. In the morning, simply mix the wet and dry ingredients together, pour oatmeal mixture into your prepared baking dish and bake as recipe suggests.

      Can you used oat milk or coconut milk instead of almond milk?

      I loved this so much but added turmeric and chia the second time I made it for a more prominent earthy tone to it. So so so good.
